PRINTERS REGISTER-HOOK.

Specificationof Letters Patent.

Patented Sept. 19, 1905.

Application filed April 11, 1904.. $erial1lo. 202,523.

To aZZ whom it may concern.- Be it known that I, JOHN KYLE, a citizen of the United States, residing at Philadelphia, in

the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Printers Register-Hooks, and I do hereby declare the following to be a full, clear, and exact description of the invention,"such as will enable others skilled in the art to which it appertainsto make and use the same, reference being had to the accompanying drawings, and to figures of reference marked thereon, which form apart of this specification. i

The objects of this invention are to provide a hook which will occupy less space between the plates to be clamped, and thus enable them to be set closer together, whereby a greater number of printing-plates of a given area may be assembled Within a given form; to simplify the operation and reduce the labor of making up forms from a number of printing-plates; to enable certain plates to be changed or removed without changing the position of other plates in the form or removing the same from said form, and to secure other advantages and results, some of which may be referred to hereinafter in connection with the description of the working parts.

The invention consists in the improved printers register-hook and in the arrangements and combinations of parts of the same, all substantially as will be hereinafter-set forth, and finally embraced in the clauses of the claim. I

Referring to the accompanying drawings, in which like numerals of reference indicate corresponding parts in each of the several figures, Figure 1 is front elevation of the improved register-hook. Fig. 2 is a rear elevation of the same. Fig. 3 is a side elevation. Fig. 4is a section taken on line y of Fig. 8, and Fig. 5 is a section taken on line as of Fig. 1,

In said drawings, 6 indicatesa metallic box or hollow block closed at the sides and bottom and open at the top, said box or block being adapted to fit amongthe type-furniture set in the chase and hold the printing-plates in proper place. The front and rear plates 7 and 8 of said box are preferably separably held on dowel-pins 9 to the body portion 10 of the box or block, which body is preferably of a Ushape in general outline in end view, as in Fig. 4. The front plate 7 is bored out near the center thereof, as indicated in Figs. 1 and 5, the boring being countersunk both at its outer and inner ends, the outer recess, formed by countersinking, being adapted to receive the head 11 of the screw 12 and the inner recess being adapted to receive the flange 13 of a traveling nut 14. The rear plate 8 is also bored out and is threaded to receive the screw 12, which latter extends from the front plate 7 through the chamber in the body of the box and through a nut 14, to and into the threaded rear plate, and when screwed up said screw 12 serves to hold the front and rear plates firmly to the body 10. At opposite sides of the said screw, a little distance therefrom, the vertical walls of the body pro vide slideways or bearings 16 17 for a hookblock 18, which at its upper edge lies flush with the tops of the front plates and extends downward to the bottom of the chamber in the. body portion 10, whereby there will be no pressurebrought upon the nut 14 or screw 12 in a direction perpendicular thereto. The nut is flanged, as at 13 19, to engage the opposite sides of the block, so that when the nut is turned on the screw in either direction the said block will be moved lengthwise of the screw. The flange 1 4 is radially grooved to receive a pin or implement for turning said nut.

The vertical wall 20 of the body portion 10 is somewhat lower than the other vertical walls, and the hook-block at the book 21 is extended laterally over said wall, the extension 22, carrying the hook 21, bearing directly down on said wall and lying vertically flush with the outer side of said wall, as in Fig. 4. Said'extension 22 also projects rearward, as shown in Fig. 3, and the rear plate 8 at one end of its upper edge is recessed, as in Figs. 2 and 3, to receive the rearwardly-projecting extension and enable the back of thehook to be brought flushwith rear Wall of the box or hollow block 6.

By this construction in practice the edge of the printing-plate is or may be brought within one thirty-second of an inch, more or less, of the back of the hook and the back surface of the block, with which said hook-back may.

-nut-turning pin or implement may be inserted between said printing-plate and the rear plate 8 and operated in a plane parallel with the said rear plate.

Having thus described the invention, what I claim as new is 1. The improved printers register-hook, comprising the box-like body having a front and rear plate provided with bearings for a screw, a screw in said bearings, a flanged nut on said screw and a sliding block engaged by said nut and operated thereby, the said block having a hooked extension lying in the plane of one of the flanges of the nut and extending over one of the side walls of said box-like body, substantially as set forth.

2. The improved printers register-hook, comprising the box-like bod y having front and rear plates provided with bearings for a screw, a flanged nut on said screw and a sliding block engaged by said nut and operated thereby, the said block having a hooked extension lying in the plane of one of the flanges of the nut and extending over one of the side walls of said box-like body and projecting rearward from said sliding block and adapted to overlie the rear wall or plate of said box-like body, substantially as set forth.

3. In a printers register-hook, the combination with the box having a rear wall recessed at the top near one end and having a low side wall, and a screw arranged in said recessed rear wall and extending to the opposite wall of the said box, of a sliding block arranged in said box and having ahook projecting therefrom over said low wall and adapted to enter the recess of the rear wall and a nut having agrooved flange the plane of which lies in the plane of the hook, substantially as set forth.

4:. In a printers register-hook, the combination with the box having a rear wall recessed at the top and a low side wall of a sliding block I JOHN KYLE.
